TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES E. STRODE, of Litchfield, in the county of Montgomerand State of Illinois, have invented a newA and improved Grain Ventilating and Drying Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereoiwhich will enable th'ose skilled in the art to make and use the same, 'reference being had to the accompanying drawings, forming part oi" this specification, in which- Figurel is al vertical section of my invention taken in the line :t n, fig. 2.

Figure 2, a vertical section of the same taken in the line y, fig. l.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved apparatus for Ventilating and dryinggrain stowed away in bulk, and consists in having one or moreair-ducts passing through the bin, box, or granary, in which the grain is piaced, Said duct or .ducts Obeing composed of slats arranged one above the other with spaces between, with openingsl in thesides of the bin, box, or granary for the adxnission of air into the duct or ducts, as hereinafter fully shown and described, whereby the grain will be thoroughly ventilated and dried.

A represents a bin, box, or granary, in which the dampgrain is stowedor placed in bulk, and B is an airduct, :of inveitcdv-i'orm in its transverse section, that is to say, with an open bottom and inclined sides meeting attheir upper edges, (sce iig. 1.) The sides of the duct are composed of slats, a, placed` one above the other, and inclined in their transverse section -from their inner edges downward towards their outer edges, and spaces, b, are allowed between the slats for the escape of air from` the duct. The duct extends entirely across the box, bin, `or gnanary A, and is slightly inclined from a horizontalposition, as shown in iig. 2, and in the sides of the bin, box, 'or granary there are made openings, c, of triangular form, corresponding to the form of the ends of the duct and in line therewith7 said openings being provideddwith doors or covers, d d. When these doors or covers dia-re opened, air is 'admitted into the duct and escapes through the spaces Z1 between the slats a, and

also escapes through the openy bottom of the duct through the mass ofgrain, causing the same to be thoroughly. Vventilated and dried. The slats a, arranged as shown, admit of a very open'duet, one which will produce a thorough ventilation, and which the grain cannot enter, or choke or clog. up, as' is'the case frequently with perforated tubes which are used for the purpose.

Having thus described my invention, I claim as n ew, and desire to secure by Letters Patent- The grain ventilator and dryer, consisting of the inclined slats a, with spaces, b, between them, when constructed and arranged as herein set forth and for the purpose specified.

- JAMES E.v STRODE.
